Voigtlander SL 15mm f/4.5 - symmetrical design ? - Klaus - 12-10-2011 I'm tempted but if it has the same symmetrical design like the Leica M variant it would be pointless.

Voigtlander SL 15mm f/4.5 - symmetrical design ? - Klaus - 12-10-2011 Ah, forget it. I just saw some images taken with the D40. No good. Voigtlander SL 15mm f/4.5 - symmetrical design ? - Brightcolours - 12-10-2011 How can it be symmetrical at 15mm? It has to be retro-focus, does not not? *edit: Oh wait.. now I get it. The mirror has to be permanently up to use it. How did they do that with a D40?

[/quote] Well, by hand. :-) Actually I was in contact with a Pentax K5 user who did just that as well. Voigtlander SL 15mm f/4.5 - symmetrical design ? - Rover - 12-10-2011 The 12/5.6 was also made in a similar version I believe. Back in the film days, it must have been cool. Now the market is awash with ultrawides.

[/quote] well, it sure looks like it will stick at least 2cm if not more into the body from the mount. It seems to work on a D5, but not surprisingly, vignetting is an issue: http://www.16-9.net/lens_tests/15mm_test1.html Voigtlander SL 15mm f/4.5 - symmetrical design ? - Klaus - 12-10-2011 [quote name='photonius' timestamp='1323549634' post='13602'] well, it sure looks like it will stick at least 2cm if not more into the body from the mount.

The rear portion of the lens would, most likely, reside completely within the necessary adapter. However, the vignetting is a showstopper.
